------- Additional Comments from Yael <yael.aharon at nokia.com>
Frame flattening algorithm requires that layout always starts from the main
frame, since layout of subframes impacts the layout of their parents. There are
places in the code that call view->layout() not on the main frame. Instead of
changing all the callsites, I changed FrameView::layout() to force layout from
the main frame if frame flattening is enabled.
In addition, postLayoutTasks can trigger relayout, so make it use the timer
even more.
